HENRY MONTGOMERY AND SIMEON HOWES, OF SILVER GREEK, NEW YORK.

GRAIN-SEPARATOR.

Specification forming partof Letters Patent No. 23,039, dated February 22, 1859; Reissued October To all whom it may concern:

Be it known that we, HENRY MONTGOMERY and SIMnoN Howns, of Silver Creek, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Grain-Separators; and we hereby declare that the following is a full, clear,and exact description of the same, reference being bad to the accompanying drawings, making a part of this specification, in which- Figure 1 represents an end view of the machine; Fig. 2 a vertical section of Fig. 1 in the line 1-2; Fig. 3 a horizontal section of Fig. 2 in the line 3-4 and Fig. 4: a hori zontal section of Fig. 2 in the line 56.

The letters of reference indicate the same parts in the different figures wherever they occur.

Our improvements relate to the combined may be constructed as follows: A'suitable frame work (A) sustains a metallic cylinder (B) perforated with rows of vertical slots, of such a width as to admit of the passage of dust and dirt and to retain the grain. Through the center of the cylinder B a vertical shaft E passes sustained in position by the step F and the bearing Gr. Within the cylinder B and attached by arms at the bottom and by a circular disk eat the top to the revolving shaft. E is a series of fan beaters H.

Upon the top of the frame A is placed a horizontal fan case 1, within which, upon a prolongation of the shaft E, revolves a suction fan composed of any suitable number of leaves connected by arms with the shaft E; two arched flues extend side by side over the top of the machine one of them K, continues vertically down one side of the machine almost to the floor, the other L, terminates on the same side at about the level of the bottom of the fan case. These flues discharge on the opposite side into chambers M and N, separated from each other by a continuation of the partition between the fines K and L. They are formed laterally by a vertical continuation of the top covering of the lines and by an inclined board resting upon the upper angle of the fan case; resembling inverted cones in their vertical section as shown in Fig. 2. Within the cylinder B, and attached thereto are several horizontal annular ribs 0.

An outlet flue P extends from the bottom of the securing cylinder B to the lower end of the flue K, and an inlet flue or passage Q extends from the bottom of the flue L into the upper end of the same cylinder, the flue Q, 1s open upon its upper side at a. A hopper R is placed upon the outside of the flue L to receive the grain which passes from thence through an aperture into the said flue. An inclined board S, extends nearly across the chamber N, having immediately beneath it an aperture (V) through the exterior casing. Beneath this is another inclined board (T) with an aperture closed by a hinged valve (7)). At the lower angle of the casing or bottom of the chamber is an outlet furnished also with a valve 0. The above description of the chamber N, and its appurtenances will suffice .for the chamber M, as they are precisely alike in size, form, and. in interior arrangement. A chamber W, is separated from the chamber N by a slide (d). It is placed immediately above the fan case, and opens into it, by a large aperture corresponding with a similar one in the top of the fan case. The chamber X is placed immediately above the fan case behind'W', is of the same size and form, and bears a similar relation toM that W does to N. A driving pulley (Z) is fixed upon the lower portion of the shaft E. Side boards C, areattached to the posts of the frame A and extend nearly to the bottom of the cylinder, forming in connection with top and bottom boards, an outer casing(D)which communicates by means of the tubes n with the fan case.

The following is a description of the operations of the machine when employed in separating and cleaning wheat. The shaft E, being put in motion in the proper direction, the fan produces powerful currents of air in the direction of the darts, through the fines. The wheat passing from the hopper into the flue L, is met by a current of air which enters through the opening a, which may be controlled or regulated by a slide or gate. This takes out smut-balls, chess, light grains, chaffdust, &c., and carries them up the flue L, the heavy wheat passes through the spout Q, to the rotating disk 6, which distributes it, equally by centrifugal force to the inner circumference of the cylinder B, where it is acted upon by the fan beaters H, which by their construction and rapid motion draw in a current of air through the opening 2', driving the dust which is disen gaged, through the slots in the cylinder, into the outer casing D, whence it is taken up by the draft through the tubes a, into the fan case and discharged therefrom, through the spout I, which may be continued into another apartment or through the exterior wall of the building.

The annular ribs 0, perform an important function, in retarding the passage of the grain through the cylinder, causing it to be exposed much longer to the action of the heaters, and to the currents of air caused by the heaters through the slots. As the grain passes from the spout P, into the flue K from the scour-er, it is met by another current of air (which may be regulated by a slide or gate) which takes all the remaining chess and light stuff and carries it up, and over the top of the machine, letting it fall upon the inclined board S. As it passes from this to the inclined board T, it is further cleaned by meeting another current of air, which enters at V in any desired quantity, the dust and chalf passing up into the chamber X, and thence into the fan whence it is discharged through I. The valve Z), is kept closed by the pressure of the atmosphere until a sufficient quantity of light grain, &c. has accumulated thereon, to overcome the resistance, it then opens, and discharges into the next chamber V. While the valve 6, is open the pressure of the atmosphere will keep the Valve 0, closed which will discharge in turn when the weight overcomes the resistance. By this arrangement the strength of the draft in the lines is not much impaired by the opening of the valves to discharge the light grain, &c. The light wheat which is separated at its entrance into the machine from the hopper, is carried up the flue L and subjected to similar influences to those above described.

The strength of the draft in the flues L, and M, and in the chambers respectively connected with them, being susceptible of independent regulation, it is obvious that the mass can be separated into four distinct portions viz: the-heavy wheat, light wheat, still light-er wheat, chess, &c., and the dust and chaff.

A current of air regulated in intensity according to circumstances, entering at the aperture U, beneath the inclined board S, meets thelight grain in its descent and carries the dust, and chaff up and into the fan whence it is discharged. Thus the light and defective grain is utilized for feed without further trouble or expense.

Having thus fully described our improve ments what we claim as our invention and desire to secure by Letters Patent is The aperture V, when situated immediately below the inclined board S and in combination therewith for the purpose specified.

In testimony whereof we have signed our names to this specification before two subscribing witnesses.
